It could end up being a biggie. Plenty of opportunities for people and companies to transfer money on there, or at least find reasons to part with money.
I can't remember if it's publicised much but FB definitely have a "want" button (or actions to that effect) in the works. There are hints of it in the timeline such as "books I'd like to read" etc.
